IMPROVEMENT IN HEATER AND FEEDER FOR STEAM-BOILERS.

Specication forming part of Letters Patent No. 187,825, dated February27, 1877 application filed IIanuary 8, 1877.

To all whom 'itrmay concern:

Be it known that I, ALEXANDRE DEBEAU- MONT, of Philadelphia,Pennsylvania, have invented a new and useful Improvement in Heater andFeeder for Steam-Boiler, of which the following is a specification:

The-main object of my invention is to utilize the whole or-a portion ofthe exhaust steam of a steam-engine, by forcing it into a-boiler with asupply of water, in the manner described hereafter.

The figure inthe drawing is a vertical section of apparatus for carryingmy invention into effect.

A is the cylinder, to Which is adapted a plunger, B, the latter beingreciprocated in the present instance lfrom a shaft, D, through themedium of au eccentric, c, and rod b, and the shaft being driven by theen gine.

At the bottom of the cylinder is a tubular i projection, d, the upperend of' which forms the seat for a valve, e, which rises, when theplunger is moved upward, and permits exhaust steam to enter the cylinderfrom the pipe E, which communicates with the exhaustpipe of asteanrengine.

Water is also admitted in the form of a jet to the cylinder, beneath theplunger. through the pipe F, which communicates with a hydrant orreservoir, a check-valve,'f, in the pipe F, opening on the ascent of thepump-plunger, and closing on its descent.

G is the discharge-pipe, through which and through the chest H,containing a check-valve, the exhaust steam may be forced directly intothe boiler.

As the pump operates continuously, however, I nse, in connection Withthe pipe G, a devicefor automatically regulating the amount of Waterwhich passes into the boiler, so that it will accord with the.requirements of the latter.

'Ihis device 1 will now proceed to describe:

The force-pipe G communicates with the chest I, and the latter, througha pipe, G', with the boiler J. Within this chest is a regulatingvalve,m, which is connected by a rod, lo, to a piston, n, in a cylinder, K,the latter communicating at the top through the pipe L with thesteam-space of the boiler, and having a direct communication belowat'all times with the outlet-passage q of the chest I, and consequentlywith the Water-space of the boiler.

The position ofthe piston 'n in the cylinder K is governed by the heightof the Water in the boiler, and when the water is at its proper levelthe lateral openings in the regulatingvalve coincide with openings inthat part of the chestin which the valve operates. so that the exhauststeam, combined with water, will pass freely through the chest into theboiler. Should the Water inthe boiler, however, rise above its properlevel, the piston n and valve m will also rise and open the lower port win the chest I, through which port as much of the combined exhaust steamand water will cylinder K, and its float n, carrying a valve,

m, with the chest l, its two sets of ports, and its Waste-pipe Q, as setforth.

In testimony whereof I have signed` my name to this specification in thepresence of twosubscribing witnesses.
